To all whom it may concern:

Be it known that I, CYRUs WV. BRIDEGUM, a citizen of the United States, residing at Hainesport, county of Burlington, and State of New Jersey, have invented a certainnew and useful Improvement in Railway-Ties, of which the following is a specification.

My invention relates to a new and useful improvement in railway ties, and has for its object to provide an exceedingly simple and effective construction in which two metallic sections in the shape of channel irons or the like are so bolted together as to hold in place wooden or metallic support-blocks, which latter may be readily removed, when occasion requires.

A further object of my invention is to provide against the possibility of the spreading of the rails when secured to the ties, and a still further object of my invention is to provide for weighting down the ties when placed in the road bed and also to prevent the crawling of the ties.

With these ends in view this invention consists in the details of construction and combination'of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction in detail referring by letter to the accompanying drawing forming a part of this specification in which Figure 1, is a plan view of a tie made in accordance with my improvement, showing the wooden supporting blocks fitted between the sections of the tie and the rails secured thereto. Fig. 2, a side elevation thereof. Fig. 3, a section at the line YY of Fig. 1. Fig. 4, a section at the line X-X of Fig. 1. Fig. 5, a detail view of one of the retaining straps. Fig. 6, an enlarged section at the line Y-Y of Fig. l, the supporting blocks and bolts being omitted. Fig. 7, a view similar to Fig. 6, the upper inner flanges of the sections of the tie omitted. Fig. 8, a plan view similar to Fig. 1, showing the metallic supporting blocks inserted between the sections of the tie. Fig. 9, an enlarged perspective of one of the supporting blocks. Fig. 10, a similar view showing the thrust plate secured to the supporting block. Fig. 11, a similar view showing the supporting block bolted between the sections of the tie, and the clamp plates in place thereon, and Fig.

12, a detail perspective of the retaining strap used in connection with the metallic supporting blocks.

In carrying out my invention as here embodied, A and A represent the two sections of the tie, each of which is made of sections of I-beam, and the central portions of these sections are bent outward, as clearly indicated in the drawing. In the inner surfaces of each of the sections is riveted or otherwise secured the stop strips B, and when the wooden supporting blocks C are being used, these blocks are fitted between the arallel ends of the sections so as to abut agamst the stop strips and the blocks of the sections are secured together by the bolts D. To prevent any endwise movement of the supporting blocks, I provide the retaining straps E, which are U-shaped and-held in place by the end bolts D.

The rails F are secured in place by the ordinary spikes G, being driven into the wooden supporting blocks and to avoid the spreading of the rails I prefer to form the holes G, in the inner flanges of the sections A and A for the passage of certain of the spikes, so that said spikes will have a metal backing.

In practice when the wooden supporting blocks become worn, they may be withdrawn and turned end for end thus further increasing their life.

The sections A and A may be made of comparatively light material, and when they are put in use, the tamping of the ballast in the space formed by the bending outward by these sections will add suficient weight to the tie to cause it to lie properly in the road bed, and the increased Width of the center of the tie, due to the bending outward of the sections will prevent it from shifting endwise in the road bed and also permit it to spread lengthwise to a limited degree when the thrust of the train wheels is sufficient to bring this action up, thereby forming a cushion, which will greatly modify all shocks due to a train turning sharp curves.

The fact that the wooden supporting blocks are of comparatively short length greatly reduces the cost of the tie, and as these blocks can be renewed from time to time without interfering with the remainder of 1316 tie, the cost of maintenance is lessene In Figs. 8 to 12 I have shown a slight i may have their top inner flanges omitted as modification of my improvement, in which I metal supporting blocks are substituted for the wooden supporting blocks, in which case H represents the metal supporting block, the latter being formed from the plate and having a cut away portion H to give easy access to the interior of the block.

I represents the thrust plates, one of which is secured to each of the supporting blocks, and these thrust plates act as chairs for the rails and also their upper edges hold the clamp plates J against the thrust of the rail, said clamp plates serving to hold the rails down upon the thrust plates.

The supporting blocks H have formed therein a series of holes K for the passage of the bolts L which hold them in place and also hold the sections of the tie together, the retaining strap M is also held in place by the end bolts and prevents any outward movement of the supporting blocks.

Of course I do not wish to be limited to the exact details of construction here shown, as these may be varied Within certain limits without departing from the spirit of my in vention, as for instance the sections A and A shown in Fig. 7.

Having thus fully described my invention what I claim as new and useful is- 1. In a railway tie of the character described, two sections in the form of I-beams, said sections being bent outward at their centers, supporting blocks secured between the parallel ends of the sections, stop strips secured to the sections to limit the inward movements of the supporting blocks, and retaining straps secured upon the'ends of the sections to prevent the outward movement of the supporting blocks, as specified.

2. The herein described combination of two sections in the form of I-beams which are bent outward at the center so as to form a space for the reception of the ballast when placed in the road bed, supporting blocks secured between the parallel ends of the sections, thrust plates secured upon the supporting blocks, and clamp plates for holding the rails in place, as specified.

In testimony whereof, I have hereunto aHiXed my signature in the presence of two subscribing witnesses.
